Unity（Android版）和Android原生APP簡單實現版本更新

版本檢測接口說明：
（1）請求post，無參數
（2）調用地址：http://www.baidu.com/rs/ver/info
（3）返回結果：
{
    "verCode": "2",
    "verName": "0.1.1.20170428_beta",
    "forced": false,
    "updateMsg": "優化部分功能",
    "apkURL": "http://www.baidu.com/meiriyiti_app/V0.1.1.20170428_beta.apk"
}

原理1（支持Android原生開發）：

①將最新的apk掛載到自己的網站；

②在APP進入的第一個頁面或者版本更新的的入口調用后台版本更新接口，請求到最新版本信息，獲取手機上APP的版本號，進行對比。

③如果服務器的版本號比手機安裝的版本號大的話，就提醒用戶更新最新版。

Android原聲版的我這里做了通過apkUrl來自動下載和安裝，下面是自動安裝的工具類和調用時候的代碼：

 

調用代碼：

//聲明
  private UpdateVersionUtils downloadUtil;
//初始化
  downloadUtil = new UpdateVersionUtils(getContext());

//在獲取服務器的新版本信息后調用
downloadUtil.isNewVersion(getActivity(), verCode, appVersionCode, verName, apkURL, updateMsg, false);

下面是兩個用到的工具類 ：

import android.app.AlertDialog;
import android.app.DownloadManager;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;

②如果服務器的版本號比手機安裝的版本號大的話，就提醒用戶更新最新版。

③在Assets/Plugins/Android/bin目錄下添加一個jar包(網盤)，如果有需要的朋友可以私信我。

點擊更新按鈕的時候調用以下代碼：

②Unity的Android版app的跳轉應用市場更新。
